OXFORD INSTRUMENTS SHARES JUMP 42 PENCE

By CBR Staff Writer

Oxford Instruments Plc’s shares jumped 42 pence to 294 pence after the company announced that it has satisfied IBM that its X-ray lithography electron storage ring is sufficient, to be shipped to its integrated chip facility in New York: although the synchrotron is not yet at full specification, shipments will start from the Oxfordbased company in the fourth quarter of this year; no information was given about when the device will actually be ready for use in chip fabrication; Oxford has been testing the ring for two months and it has now succeeded in storing an electron beam of over 50mA with a lifetime of one hour at the full electron beam energy of 700 MeV; electron rings can be used as an X-ray source to etch denser circuitry and greater mass memory chips, than the conventional ultra violet light lithographic process but existing generators to produce the required intensity of X-ray source are too large for commercial uses; Oxford says that Helios can be installed in a silicon wafer factory and that it would be suitable for fabricating 64M-bit and 256M-bit memories.
